When you have a wrinkled shirt and there’s no time to heat the iron and set up the ironing board, toss it in the clothes dryer with an ice cube and run for 5 minutes. As the ice melts it turns into steam that will relax the shirt’s fibers and remove the wrinkles. Don’t over dry or you’ll get new creases! Hang or don the shirt immediately. This works great on tees and casual shirts, NOT dress shirts, those still need to be ironed.
